4.2. Connecting the Transmitter (TX)

1. Connect Video Source: Connect your video source (e.g., DSLR camera, laptop, game console) to the HDMI IN port on the TX unit using an HDMI cable.
2. Power On: Ensure the TX unit is powered using one of the methods described above.

4.3. Connecting the Receiver (RX)

1. Connect Display: Connect your display device (e.g., TV, monitor, projector) to the HDMI OUT port on the RX unit using an HDMI cable.
2. Power On: Ensure the RX unit is powered using one of the methods described above.

4.4. Pairing (Plug-and-Play)

The WL085P system is designed for plug-and-play operation. Once both TX and RX units are powered on and connected, they should automatically pair and begin transmitting video. No additional apps, Bluetooth, Wi-Fi, or internet connection is required for basic operation.

5. Operation

5.1. Transmitter (TX) Input Modes

The TX unit supports two primary input modes:

• Built-in Camera Input: Upon startup, the TX unit defaults to its built-in 2MP camera as the video source. The live feed will be displayed on the TX's 2-inch preview screen.
• HDMI Input: If an HDMI cable is connected to the HDMI IN port, the system will automatically prioritize the HDMI input over the built-in camera.

5.2. Multi-Cast Transmission (1 TX to 5 RXs)

The WL085P system supports transmitting video from a single TX unit to up to five RX units simultaneously. This allows for multi-room video sharing or monitoring across multiple displays.

• To utilize this feature, simply power on and connect additional RX units as described in the setup guide. They will automatically connect to the active TX unit.
• Note that increasing the number of connected RX units or barriers in the environment may slightly reduce the overall transmission distance.

5.3. Real-time Monitoring

The RX unit's 7-inch LCD screen provides real-time monitoring of the transmitted video, offering convenience for various applications like video shooting, presentations, or home entertainment.

6. User Tips

• For optimal transmission range and stability, ensure a clear line of sight between the TX and RX units. Avoid placing obstacles like walls or large electronic devices directly in the transmission path.
• When using multiple RX units, consider the environment and potential interference. In complex environments, the effective range might be reduced.
• Always ensure both TX and RX units are adequately powered. Using fully charged NP-F batteries or a reliable power adapter/power bank is recommended for uninterrupted operation.
• If experiencing signal drops or instability, try repositioning the TX and RX units to minimize interference and maximize line of sight.
• The TX unit's built-in camera and microphone are convenient for quick setups. For higher quality or specific audio needs, connecting an external camera and microphone via HDMI is recommended.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the units. For the LCD screens, use a microfiber cloth specifically designed for electronics. Do not use liquid cleaners or abrasive materials.
• Storage: Store the devices in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove any installed batteries.
• Handling: Handle the units with care to avoid dropping or physical damage. The antennas are crucial for signal transmission; avoid bending or damaging them.

8. Troubleshooting

8.1. No Signal on Receiver (RX) Screen/Connected Display

• Check Power: Ensure both the TX and RX units are properly powered on.
• Check HDMI Connections: Verify that all HDMI cables are securely connected to both the video source and the display.
• Line of Sight: Ensure there are no significant obstructions between the TX and RX units. Try moving them closer or adjusting their positions.
• Interference: Move the units away from other wireless devices (e.g., Wi-Fi routers, microwaves) that might cause interference.
• Re-pair: Power cycle both the TX and RX units to force a re-pairing.

8.2. Poor Video Quality or Dropped Frames

• Distance: You might be at the edge of the transmission range. Try moving the units closer.
• Obstacles: Reduce the number of obstacles between the TX and RX.
• Interference: Check for other wireless devices operating on similar frequencies (2.4GHz/5GHz).
• Source Resolution: Ensure your video source is outputting a compatible resolution (up to 1080P@60Hz).

8.3. Audio Not Synchronized

• Check Source: Ensure the audio is correctly outputting from your video source.
• TX Microphone: If using the TX's built-in microphone, ensure it is not obstructed.
• HDMI Audio: If using HDMI audio, verify the source device's audio settings.
